The following thirteen Patch Tuesday updates / patches have been released by Microsoft for the April 2016 Update deployment.

Cumulative Security Update for Internet Explorer (3148531)
This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

MS16-038 – Critical

Cumulative Security Update for Microsoft Edge (3148532)
This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users with administrative user rights.

Security Update for Microsoft XML Core Services (3148541)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user clicks a specially crafted link that could allow an attacker to run malicious code remotely to take control of the user’s system. However, in all cases an attacker would have no way to force a user to click a specially crafted link. An attacker would have to convince a user to click the link, typically by way of an enticement in an email or Instant Messenger message.

MS16-041 – Important

Security Update for .NET Framework (3148789)
This security update resolves a vulnerability in Microsoft .NET Framework. The vulnerability could allow remote code execution if an attacker with access to the local system executes a malicious application.

MS16-042– Critical

Security Update for Microsoft Office (3148775)
This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

MS16-044 – Important

Security Update for Windows OLE (3146706)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. However, an attacker must first convince a user to open either a specially crafted file or a program from either a webpage or an email message.

MS16-045 – Important

Security Update for Windows Hyper-V (3143118)
This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an authenticated attacker on a guest operating system runs a specially crafted application that causes the Hyper-V host operating system to execute arbitrary code. Customers who have not enabled the Hyper-V role are not affected.

MS16-046 – Important

Security Update for Secondary Logon (3148538)
This security update resolves a vulnerability in Microsoft Windows. An attacker who successfully exploited this vulnerability could run arbitrary code as an administrator.

MS16-047 – Important

Security Update for SAM and LSAD Remote Protocols (3148527)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker launches a man-in-the-middle (MiTM) attack. An attacker could then force a downgrade of the authentication level of the SAM and LSAD channels and impersonate an authenticated user.

MS16-048– Important

Security Update for CSRSS (3148528)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow security feature bypass if an attacker logs on to a target system and runs a specially crafted application.

MS16-049 – Important

Security Update for HTTP.sys (3148795)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow denial of service if an attacker sends a specially crafted HTTP packet to a target system.
